I seem to be missing some information from my stack trace, here is what i'm getting: at Foo.Bar(DataTable table) in D:FooBarauthoringApp_CodeFooBar.vb:line 87 Where is the rest of the stack trace infomation?
[Code]...
For debugging purposes, I would like to create a log file showing each function that gets entered. I understand everytime a function is entered, it is added to the stack trace. Is it possible to get events from the stacktrace everytime a new function gets added so that I can log it? I don't want to write log messages to every one of my functions in code, I would like to automate it. OR, is there another way? (I am using VB 2008 Pro)
View 3 RepliesIs there a way in .NET (VB.NET or C#), when an exception happens, to dump the stacktrace of each thread? Basically I would like to reproduce what happens in Visual Studio's Debug->Threads window to see what each thread was doing when the exception happened
View 2 RepliesI've got some code which errors and I'm using the stacktrace to find out what the line number is but it seems to be giving me the wrong number
[Code]...
It seems to give me the line number of where the StackTrace is starting rather than the line number of what is causing the exception
I just did some analysis by using a global function which is called GetCallingMethod in my case.
Mostly it works great. But some cases the application is blocked. It is blocked when closing the application. When going to "pause" in Visual Studio, it stays on the new StackTrace line forever.
In my application I am using third party references, multithreading and several classes. But all that should not be a problem and should not lock the tracer class as far as I imagine. I am using Visual Studio 2010 Ultimate in this case.
This line will never be left in development area. Application will is frozen. Try/Catch will not force the procedure.
I'm trying to show the line numbers with a stack trace when an exception is thown in my app.
This code is in the UnhandledException of ApplicationEvents:
e.Exception.StackTrace.ToString
It currently returns:btnOK_Click(Object sender, EventArgs e) at with no line number at the end.
I have set the project to create debugging info in Project Properties > Compile > Advanced compile options > Generate Debug Info = pdb-Only, and deployed the PDB file with the app, but still I don't get any line numbers.
I'm using VS2008 Standard, vb.net.
The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

I was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?
Public Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal _
lpSubKey As String, phkResult As Long) As Long
Goal: Find information on how to implement a method which will check if a certain DSN exists, and then if it does, extract the information and use the information for connection purposes.
I have a text box where i am entering numbers of double datatype andon the Keytdown event of the textbox some checks take pace and in certain circumstances I want to be able to stop the user from entering other information until they enter the right information in the textbox (where it says right here) . now when I say exit sub the textbox somehow loses focus . but this is not how I want it to be I want the textbox to remain with the focus so the user can change the information . How can i go about this. And the other thing is why is my txtDestPayRate1.Focus() just befor the exit sub not working?
Private Sub txtDestPayRate1_KeyDown1(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles txtDestPayRate1.KeyDown
If e.KeyCode = Keys.Enter Then

I am designing a backup/restore utility for work.atm i have been able to populate field for PC name, IP address, MAC address, number of printers installed on the PC but i am wondering is it possble to get all the printer information 'with the click of a button' to print all information like the prnmngr.vbs script down.I am able to run a batch file but i wanna get it to go from that app or even embed to batch file to the app and run it form there .
View 4 RepliesI am using VB2005 and trying to put an application together.What it needs to do is retrieve information from a binary file, possibly alter that information, and put it back into a new file.The file is a .wav file with data appened to the end. There is an additional section at the end of the .wav file which stores xml data.I have found that if I open this in a hex editor and make a 1:1 swap on any of the bytes that the application that the file is for can still read the XML.If I tried to add or remove characters from the XML then it would not read. I located a header byte and incremented it to resolve this.
This worked as an excellent bandage to do conversions where the data always needed to be changed to the same thing.What I have been asked to do is build logic that allows for different things to happen depending upon what data is contained within the file.The method that I am currently trying to impliment is:
Read through the file with a system.io.binaryreader
Searche for a bytestream that will signal data is coming
For example:
If System.IO.File.Exists("C: est estread.wav") Then
Dim findit() As Integer = New Integer() {&H3C, &H55, &H73, &H72, &H44, &H65, &H66, &H30, &H31, &H30}
Dim i As Integer[code].....
And then extract all the data till the end of element marker "<" It seemed like there should be a better way and I was looking for some insight. If I proceed with this method, I will have to read the file one time to gather the information and then a second time to write it all out with the header modified for length.This is my first experiene with working with binary files in this way.Also,I've been experiementing with building a string and slapping it back in at the end using the binarywriter.write(string) method.I noticed that it was putting in header characters before the string.These seem to change if I change the length of the string.At one point it was d0 07. Later it became e7 07. Does anyone know of a way to prevent this header from being inserted?
I tried a for each loop to grab all of the characters from the string, convert them to a byte array and deposit the byte array into the file, but the header remained the same. When I write the byte array generated from a system.io.binaryreader I do not get this header.
I have a fair bit of experience with VB.NET and C# (In this case I chose VB.NET, blame my laziness), but I do most of my professional work using PHP. I have no experience what so ever in using any database with VB.NET let alone MySQL.Just FYI, at the moment I am only trying to Query the database to gather the information required to activate. The Activation wizard and algorithm building (which is finished anyway), and everything else will come soon. I chose the MySQL database because I have experience with it, and it seems the best option for remote usage.The whole idea already works in PHP, I'm just have major issues moving it accross into VB.NET (Using the MySQL Connector.NET);I understand the basics, and all I need to know how to do is Count Rows and gain access to the other information in a row based on provoided information (in PHP, through mysql_ result)
So, here goes nothing, this is the Query code I am using in PHP to complete the job I want to do in VB.NET. [code] As you can see, I basically need to get the PHP code into VB.NET to fit into the 'btnQueryDB.Click' Command in VB.NET. By Equivalent, the Product ID in VB.NET will come from 'txtPID' and similar, Serial Number will come from txtSNUM. Once counted to be 1, the Activation Code and Status will be fed into 2 other text boxes in the form. (acCode, and acStatus).
I'm doing an experiment on WPF and MVVM, and while coding the ViewModel on Vb.net I noticed this red wavy lines under my ObservableCollection(of T)s T_T
Anyway, the application is in WPF & VB.Net, under the .Net Framework 3.5 (I checked) and I have an 'Imports System.Collections.ObjectModel' on top of my class. Intellisense shows the other classes on System.Collections.ObjectModel except ObservableCollection.
Here's a screenshot.
So, why is ObservableCollection(of T) missing and how do I make it appear?
I am trying to publish to my hard drive so it can later be burned to CD or DVD a project I have developed and I seem to be missing that file. The person I developed it for does not have good internet access, so downloading such things as SQLExpress and DotNetFx35Client is all but out of the question. How and where do I get the file? I know where to put it on my hard drive once I have it.

Using VB.NET 2008 SP1 on Windows XP Pro SP3:
I am using an existing COM dll that works fine in VB6, on the same development machine. The VB6 app compiles and uses this dll without issue.
I start from scratch to design a new Windows Form application in VB.Net. Then when I try to add a reference to this dll, the reference is added to the references list but the path shows as <The system cannot find the reference specified>. If I select this reference in the list, the properties window shows a blank for both the reference name and the path. At the same time, a reference is added for VBA, and it shows the reference name (Interop.VBA) and path correctly.
I used dependencywalker to find the dependencies for this dll. It has 3: user32.dll, kernel32.dll, and msvbvm60.dll. So presumably I have all necessary dependent files.
I have tried un-registering, re-registering the dll. I have tried the command line switches for devenv.exe to reset settings and to launch in safe mode. I created a new user account to see if it was related.
I have tried picking the dll from the Add References, COM tab and also via the Browse tab to select the file directly. Same result all cases. I also tried putting the dll and msvbvm60.dll in my bin folder.
I don't understand how the reference name and path are missing in the properties window when the reference name is right there in the list and I select the path directly when I added it. There are no other instances of this dll registered.
I tried using tlbimp from the command prompt with verbose switch, I get the error:
System.Runtime.InteropServices.COMException - Error loading library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRAY)). I wish it would tell us what is missing.
It must be registered properly and all dependencies available for it to work in my VB6 app, Re-writing the dll is not currently an option.
